half wave rectifier circuit

The structure of the half-wave rectifier circuit is shown in Figure a. In the figure, T is the power transformer , "." is the primary side AC voltage of the power transformer, P
is the secondary side AC voltage of the power transformer , rVD is the rectifier diode, L is the DC current
of the rectified output , Uo is the DC voltage of the rectified output, R, . is the load of the rectifier circuit.     The input and output voltage waveforms of the half-wave rectifier circuit are shown in Figure 12-lb, c.     In the positive half cycle of the ground, the diode VD is forward-biased and conducts, and there is a current J. Through the diode and the load , And a positive and negative pulsating DC voltage is generated at both ends of the load Ri. In the negative half cycle of №, the diode VD is reverse biased and cut off, no current passes through the diode, and there is no output voltage at both ends of the load. The half-wave rectifier circuit only allows input AC The positive half cycle of the voltage ground passes through, and the rectified output is a half-wave pulsating DC voltage.
